#N/A Conversion

A

Aaron

Hi - how do I go about converting a value that shows #N/A to a number like 0?
I want to use the value to calculate a sum of a column but the #N/As in the
column prevent me from doing so. This is what the spreadsheet looks like:

A B
1
2 Date Count
3 11/1/2009 0
4 11/2/2009 #N/A
5 11/3/2009 0
: : :
: : :

Column A1 is the first day of the month. The formula for Column A2 is A1+1.
The formula for Column A3 is A2+1 and it keeps going until the end of the
month.

Column B1 is a formula that refers to another sheet and uses hlookup.
=IF(ERROR.TYPE(HLOOKUP(A3,Sheet1!$1:$138,127,FALSE))=ERROR.TYPE(#N/A),0,1)

On Sheet1 not all of the dates are there - the weekends are excluded from
the sheet. On Sheet2 I have all of the dates there. I'm trying to automate
Sheet2 so that if I enter the first day of the month in A3 that it'll pull
the info from Sheet1 into Sheet2 where I can calculate the sum of the
numbers. Sheet1 is more of an input area with lots of info whereas Sheet2 is
for presentation of limited information.

So basically the IF statement above is looking for a match on the date, if
it can't find the date, it should be a zero otherwise a 1 should be there.
It works if it can't find a date but if there is a date it shows an #N/A now.
I can't sum the column up if there is an #N/A. I thought that the IF
statement should work whether true or false. Can someone assist in pointing
to the right direction in fixing the statement? I'm almost at wits end with
this. Thank you! Aaron

For doing similar things, I use the ISNA function so:
=IF(ISNA(HLOOKUP(A3,Sheet1!$1:$138,127,FALSE)),0,1)

Try this:
=IF(ISERROR(HLOOKUP(A3,Sheet1!$1:$138,127,FALSE)),0,1)

Hi Tom - Thank you very much for the reply. I tried this function out and it
works similarly to what LMH replied earlier with the ISNA function. They
both work out the same. I will test further with the both of these
functions. I really appreciate your help! Thank you again! Aaron

Just be aware that ISERROR masks all errors, not just #N/A

Hi Gord - thank you for pointing that out. I didn't realize that. I will
check my calcs again and see how this function interacts with the other
errors. Thanks! Aaron
